Abstract

The invention provides a method for preparing an aluminum-plastic composite film. The bonding method of the adhesive layer is a chemical reaction, and the composite strength is obviously improved compared with the partial physical bonding method of the traditional two composite processes, and the chemical corrosion resistance is better. Good; and this aluminum-plastic composite film production process greatly reduces the requirements for equipment and raw materials, and also significantly reduces the requirements for personnel's operational quality, ensuring that the interference it receives in production is reduced and the stability of mass production is improved; its The production speed is significantly improved compared with the thermal process, which improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of composite membranes, and in particular relates to a preparation method of an aluminum-plastic composite membrane. Background technique [0002] The existing inner layer composite process of aluminum-plastic film mainly includes dry composite process and thermal process. The dry lamination process mainly refers to the traditional dry gluing lamination process used in the lamination process between the inner layer and the aluminum foil layer in the process of aluminum-plastic film manufacturing. The advantages of this process are simple operation, mature process, and high production efficiency. High; but because the inner layer of the aluminum-plastic film is directly exposed to the erosion of strong solvents and hydrofluoric acid, some ions will penetrate the inner layer material and erode the bonding structure. Once the glue fluctuates, the structure of the aluminum-plastic film will be damaged. , causin...
